Could I Have Rodents in My Mobile Home?

Can rodents be be burrowing between my floor board and the carpeting of my mobile home? Something looks like its burrowing all through my mobile home and also like through the trim of my walls. My electrical outlets are no longer flush, like something running through them, but I don't find droppings. My 3 cats also act spooked. Please help!

Keep in mind that electrical plugs can come loose after time in a mobile home, in our older home, we found that with some plugs, the screws were applied to the drywall only, not where there were studs, and these eventually wiggled loose.Yes, you could have a rodent problem. We found out after the bathroom floor caved in from moisture, that a rabbit had somehow gotten under the trailer, and chewed through the hot water line, and made a tiny hole in a water line, which was spraying a fine mist to the underside of my bathroom floor! We knew it was a rabbit as the carcass was still there.
